Development of a Laser Cladding Process Model

F. Wirth [1], K. Wegener [1],
[1] IWF, ETH Zürich, Switzerland

Additive manufacturing is attracting more and more interest. Laser Cladding is one of these additive manufacturing processes. For this a quasi-stationary physical based 3D process model is presented, which has been developed taking into account heat transfer, melt pool fluid flow ... En savoir plus

A Black-Oil Model for Primary and Secondary Oil-Recovery in Stratified Petroleum Reservoirs

A. Dollari [1], C. Chatzichristos [1], A. Yiotis [1],
[1] National Center for Scientific Research Demokritos, Greece

Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... En savoir plus

Investigation of Silicon Etching Process with COMSOL®

D. Kray [1], L. Leis [1],
[1] University of Applied Sciences Offenburg, Germany

In this work we investigate a wet-chemical silicon etching process. COMSOL Multiphysics® is used to extract local pressure values to correlate them to experimental results. The test setup consists of a box with a fixed wafer and a nozzle that injects an etchant jet onto the wafer ... En savoir plus

Sensitivity Estimation of Permanent Magnet Flowmeter

V. Sharma[1], S. K. Dash[1], G. Vijaykumar[1], B. K. Nashine[1], B. Krishnakumar[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1]Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus

3D Numerical Simulation of Resistance Sintering for Electrical Contact Applications for Breakers

J. AMOVIN-ASSAGBA¹, V. BRUYERE², P. NAMY², C. DURAND¹, S. ROURE¹
¹SCHNEIDER ELECTRIC, 31 Rue Pierre Mendes France, EYBENS, FRANCE
²SIMTEC, 5 Rue Felix Poulat, GRENOBLE, FRANCE

In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... En savoir plus

Design and Simulation of Indigenous Roll-over Sensor for Four-Wheeler Automobiles

Piyush Raj [1], Adarsh G Datta [1], Vishnu Kumar [1],
[1] Indian Institute of Science, Bangalore, Karnataka, India

In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus

Flow Optimization of a MVHR Combined with an Exhaust Air Heat Pump by Means of CFD Simulation

F. Ochs [1], M. Bianchi Janetti [1], M. Romani [2],
[1] University of Innsbruck, Unit Energy Efficient Buildings, Austria
[2] Galletti Group, Italy

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus

Application of Solution Mapping to Reduce Computational Time in Actively Cooled Power Electronics

K. Lowe [1,2], and Rao V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]Department of Mechanical, Aerospace, and Biomedical Engineering, University of Tennessee, Knoxville, TN, USA

In some power electronic applications the available coolant temperature is close to maximum and controlling operating temperature becomes more challenging, for which new thermal management schemes must be considered. COMSOL predicts the 3D fluid behavior and 3D temperature distribution ... En savoir plus

Numerical Simulation of Coupled Fluid-Solid Interaction in Digital Rock Samples

V. Das [1], T. Mukerji [1], G. Mavko [1],
[1] Stanford University, Stanford, CA, USA

Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... En savoir plus

Simulation of Helium Atmospheric Pressure Plasma Jet using COMSOL Multiphysics®

S.A. Mannion¹, Prof. T. Murakami ², C. McDonnell¹, Dr. T.A Field¹, Prof. D Riley¹, Dr. S White¹, Prof. W.G Graham¹
¹Queen's University Belfast, Northern Ireland, UK
²Seikei University, Tokyo, Japan

Atmospheric-pressure plasma jets (APPJ) are devices that generate chemically reactive species and operate at atmospheric pressure and ambient temperature for a wide range of applications. Plasmas jets produce charged particles (electrons and ions), neutral metastable species, radicals, ... En savoir plus
